I and the resulting receptacle is shown in Figuretrically thereto at 103 and at 104 to disc 105 which is rotated .by apower shaft 84. The free end of arm 29-is provided with a fork 32 havingbifurcated extremities 33. When the arm 29 swings in a counterclockwisedirection, as viewed in Figure 1, the bifurcations 33 engage the bag 25which is held within the notch in arm 23 and move the bag into the jawsof a transfer arm 34;

Transfer arm 34 is secured to a rock shaft 35 and is formed withbifurcations 36 and 37 upon the end thereof. Bifurcation 36 ,is formedwith an offset,- reversely extending jaw 38 having spaced ribs 39between which the ring 26 of a receptacle is adapted to be received.Bifurcation 37 has a movable jaw 40 journaled thereon at 41, a spring 42normally urging the jaw toward the jaw 38, being stopped in the positionshown in Figure 1 by means of a stop 43. Movable jaw 40 is provided withspaced ribs 39 in a manner similar to jaw .38 and the neck of'thebagisthus effectively received between these movable jaws.- After a bagis received between the jaws 38 and 40, the transfer arm 34 swings about4 the axis of shaft 35 and moves the bag into the position shown inFigure 4, wherein it is engaged by a rotating mechanism.

- tion. Shaft 45 is journaled inbrackets 47 and 46 and. at the lowerextremity thereof, is pro-. vided with movable jaws 49, journaled upon'shafts 50 and formed with interengaging teeth 51. A spring 52 normallyurges the jaws into engagement and dogs 53, formed on the jaws, areadapted to be engaged by a plate 54 to facilitate the movement of thejaws into a released position. Plate 54 is mounted upon an axiallymovable shaft 55, the plate being provided with a guide 56 which slidesbetween pins 57 upon bracket 48. In the position shown in Figure 5, oneof the dogs 53 is engaged by plate 54 and the jaws 49 are'separated. Inthe position shown in Figure 6, however, the plate 54 is shown in alowered position and the jaws are shown as engaging the neck of abag-like receptacle which has been moved into engaging position.

As the plate 54 descends to permit the jaws 49 toengage the neck of abag, the movable jaw 40 is moved away from the jaw 38 by means of a cam58 which is engaged by a roller 59 angularly journaled upon a shaft 60which is mounted upon an angular extension 61 of the plate 54. In thisfashion, interference between jaws 49 and 38 and 40 is avoided.

' As the bags are moved from the position occupied while being held bythe arms 20 in the position 23, the strings and tags secured thereto"are guided by means of a guidev rail 62 which may extend partiallyaround the carrier 21 and outwardly to a plate 63. A cooperating plate64 is spaced from plate 63 to form a guide groove 65 through which thestrings of the bags pass. Be-

low the rail 62 and plate 63 is a curved guide plate lie beneath theplates 63 and 64. Guide 66 terminates in a widened groove 67 into whichthe tags move, continued movement thereof causing the tags to move overa leaf spring 68 which urges the same upwardly against the bottomsurfaces of plates 63 and 64. Continued movement of the tags, as thestrings to which they are secured pass through groove 65, brings themunder longitudinal rails 69, carried by a plate 70 which is mounted uponan arm 71. The raiis 69 constitute friction shoes which serve to force.the tags upwardly and maintain the same against the bottom surfaces ofplates 63 and 64, the rails being mounted upon leaf springs 72 which areanchored at 74 upon the plate 70.

- The ends of leaf springs 72 bear upon heads '15 which are formed uponguide rods '13, upon the ends of which the shoes 69 are mounted. In thisfashion, the tags are held frictionally during the winding operation toinsure the satis factorywinding of the string about the necks of thebags. 4

Transfer arm 34 and rock shaft 35 are actuated by an arm '76 which isconnected to a link 77, pivoted to the end of a lever 78 at '19. Lever78 is joumaled upon a shaft 80 and formed with a crank arm 81 upon theend of which a roller 82 is journaled. Roller 82 is adapted to engage 93is journaled to engage the periphery of a cam 94 which is secured topower shaft 84. Reciprocating motion is thus imparted to link 88 toswing the plate '10 from the position shown in the solid lines of Figure'l to the position shown in dotted lines therein. Link 88 is alsoconnected through a universal connection 95 to an arm 96 which isjournaled at 97 upon a stationary portion of the machine." Intermediatethe ends ofarm96,alink98-isjournaledat99. 'Ihe free end of link 98 ispivoted at 100 to a bracket 101 which is formed upon plate 54. In thisfashion, link 88 serves as a means to raise and lower plate 54periodically.

In order that rollers 82 .and 93 may be maintained against therespective cam 83 and 94, springs 106 and 107, respectively, areprovided, these springs serving to maintain the elements actuated by therespective arms '18 and 90 in a normal position.

Pulley46 andshaft45withthebagenmlng jaws 49 are rotated by means of abelt 108' which is driven from a pulley 109, mounted upon -a shaft 110which is journaled in brackets 111,

carried by the frame of the machine. A second pulley 112 issecuredtoshaft 110 and is driven by a belt 113 which is mounted over a pulley.

114 which is securedto the power shaft 84. In this fashion, belt 108 iscontinuously driven .and shaft 45 rotated continuously except when therotation isinterrupted by means of a stop 115 which is secured to theshaft.v 8top'115 isformed with oppositely extendingwhichare'adaptedtobeengagedby mounted upon an arm 118. Arm 1181sjournaled at 119 and actuated by a link 120 which iseonnected atl2ltoaleverl22which'is journaled upon shaft 80 and upon which an arm 123is mounted. Arm 123 is provided with a roller 124 which is adapted toengage a cam 125 driven by the power shaft 84 and, in this fashion, stop117 is moved into the path of arms 115 to stop rotation of the shaft 45when the stop members 49 are in a plane parallel to the planes of thejaws 38 and 40. In this position, the jaws 149 may swing downwardlybetween the jaws 38 and 40 and engage the neck of the bag, the positionof which is indicated by the dotted lines in Figure 5. During thisoperation the belt slips over pulley 46.

The operation of the mechanism described hereinabove will be seen totake place in accordance with the proper spacing and formation of theearns 83, 94 and 125, together with the driving pulley 114. When the arm20 is in'the position shown at 23, the arm 29 is actuated to move theheel: of a bag between jaws 38 and 40. The transfer arm 34 is then swunginto the position shown in Figure 4 and the bag is placed beneath shaft45. Plate 54 is lowered and roller 59 cams against the cam 58 toseparate the jaws 38 and 40,

jaws 49 simultaneously swinging together toengage the neck of the bag,as shown in Figure 6. Stop 117 is then withdrawn from the path of arms11.5 and the shaft 45 is permitted to be ro hated by the belt 108.During the movement of the bag on the transfer arm, the string and tagsecured to the bag are guided by means of rails 62 in guide members 63,the string passing through the slot 65. When the bag is rotated, the tagis drawn through the guide member and between the friction shoes 69 andthe lower surface of the guide plates 63 and 64. After rotation of thebag a sumcient amount, the stop 11? swings into-the path of arms 115 andthe rotation ceases. Plate 54 is then elevated to disengage the jaws 49and the bag with the string wound about the neck thereof is dropped intoa suitable receptacle. The operation of the machine continues to passthrough cycles as outlined above.

While the invention has been describedv with specific reference'to theaccompanying drawings, it is not to be limited, save as defined in theappended c.
